<P>PROBLEM TO BE SOLVED: To provide a thin touch pad and capacitive sensor sheet. <P>SOLUTION: A touch pad 1 for detecting adjacency of an input object 100 and a position of the input object 100 when the input object 100 is adjacent to the touch pad includes: a tabular protection plate 2 having light permeability; a light guide 4 provided on the protection plate 2 and transferring illumination light L to the protection plate 2; a reflection member 6 provided on the light guide 4 and having a reflection surface 6a for reflecting the illumination light L toward the protection plate 2 side; and an electrode part 7 provided on a back surface 6b opposite to the side with the reflection surface 6a on the reflection member 6 and detecting change in capacitance between the input object 100 and the electrode part. <P>COPYRIGHT: (C)2012,JPO&INPIT |
